Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pump pressurization is used to generate fine bubbles, then bubble generation efficiency is improved, but device complexity and energy consumption increase
Solution Approach 1:
The invention extracts and eliminates the pump component from the fine bubble generation system. By using a porous body with specific pore diameter (1-100 μm) and porosity (30-80%), the system generates fine bubbles through passive flow without requiring active pressurization equipment, thus simplifying device structure while maintaining bubble generation capability
Solution Approach 2:
The porous body structure enables self-service bubble generation through its inherent physical properties. The specific pore diameter and porosity range allow liquid to pass through and generate fine bubbles automatically based on flow rate and pressure differential, without external control or additional energy input beyond what is needed to drive the flow
